The second factors : organic nutrition (20 ton/ha dose), consists of 4 types (without nutrition, cow nutrition, goat nutrition and compost nutrition). Interaction of water stress and organic nutrition treatments affects high significantly the number of leaves per plant, plant height, and root length, but affects non significantly the leave width and leave weight. The result of observation on 5^th month after plant shows that the water stress treatment affects high significantly the number of leaves per plant, leave width, leave weight, plant height, and root length. The result of organic nutrition treatment affects high significantly the number of leaves per plant, leave width, leave weight, plant height, and root length. Interaction of water stress and organic nutrition treatments affects high significantly the number of leaves per plant, leave width, plant height, and root length.
